PendingCN122643861AWaste treatmentMolten slag
The present application belongs to the technical field of industrial pollutant emission control and solid waste treatment, and particularly relates to a fly ash in-situ reduction method for waste incineration flue gas purification. A calcium-based composite powder is sprayed into a region with a temperature of 850-950 DEG C in the waste incinerator hearth by a spraying device. In the temperature zone, the active components in the calcium-based composite powder rapidly react with the acid gases such as SO2, HCl and HF in the flue gas to generate a dense slag precursor, which is mainly a stable high-density mineral phase such as CaSO4. The precursor does not rise with the flue gas due to its high density, high melting point and no low-melting-point adhesive layer on the surface, but directly sinks to the grate, and finally is discharged with the slag, thereby reducing the amount of fly ash entering the subsequent flue gas purification system at the incineration source. At the same time, the technology forms a synergistic effect with the post-furnace semi-dry / dry deacidification process: most of the acid gases are removed in the furnace, the consumption of lime in the downstream is greatly reduced, and the generation of secondary fly ash is further reduced.
